Those parts would still be rubbing without proper lubrication during the roll over wouldn't they?

Re: Lube Oil Polisher

Yes but not to the same extent. You will pump some oil into the crank, cam and rod bearings but you won't get the coverage you would get with a preoiler. I guess it boils down some oil is better than none.

You are right, oil doesn't wear out. It breaks down.

Re: Lube Oil Polisher

Ask five sailors and you'll get six different opinions . . .

For whatever (little) it may be worth --

I change oil and filter on my Yanmar every 100 hours (the genset, too). I have always changed oil and filter on my cars at 3000 miles. Diesels put a lot of cr*p into the lube oil and it cannot possibly hurt to change it more often than the 250 hours recommended by the manufacturer.

For a heavy over-the-road truck which is run a jillion miles a year, you might think hard about clever ways to extend, rather than shorten your oil change interval. But our boat engines are rarely run for more than a few hundred hours a year, so why bother with anything other than frequent changes?

I run mine about 400 hours a year, so I am changing oil and filter roughly once a quarter. It's a simple job, costing little in the way of either money or effort.
